Corteco Crankshaft Oil Seal 12019250B 40x52x7mm

Corteco Crankshaft Oil Seal 12019250B – 40x52x7mm (Timing End)

The Corteco 12019250B is a high-quality crankshaft oil seal for the timing end of the engine. Made from FPM (fluoride rubber) with a right-hand swirl design, it provides a reliable seal against oil loss at the timing cover. A leaking crankshaft seal causes oil to contaminate the timing belt or chain, leading to premature wear and potential engine damage if left unchecked.

What causes a crankshaft seal to fail?

Oil seals degrade over time due to heat cycling, oil contamination and age. Symptoms include oil staining around the timing cover, oil on the belt/chain, or a burning oil smell from the engine bay.

Is the Corteco brand reliable?

Yes — Corteco is a Freudenberg Group brand and is widely recognised as OEM-quality. Their seals are used in original equipment fitment by many major manufacturers.

How do I confirm this is the right seal for my vehicle?

Match the dimensions (40x52x7mm) and fitting position (timing end). You can also send us your UK registration or VIN and we will confirm compatibility.

Do I need to drain the engine to replace this seal?

Not necessarily — however the timing cover must be accessed, which varies by vehicle. Professional fitment is recommended.
